This invention relates to an im n-ovement in removing eotton from the bolls reparatory to ginniz; it. In the process 0 piokio cotton by hen the cotton is usually remove from tho pad or boll in. the fieid. This is a tedious and slow method, and it is the orpose of my invention to provide a mac :ne

' which is capable of mechanically removing the cotton ii'om the pod, it being understood that the cotton may he pickezlfrom the plant; W W

below the cylinders. The separator-cylinders with the (353$ thereon.

It is a so the purpose of my invontion to pro ide means whereby the pods; leaf trash, mot s, and other foreign matter may be Worked over, so as to save all of the list.

Other objects and advantages, aswell as the novel details of construction of lhisiro nntiurl, will be speeifieally described he ein-- aiter, it hoing sndorstood' that ohimgesm form, proportion, and minor lstmls of construvtion may be resorted to without do parting from the spirit of the inveirt-iouor sacrificing any of the advantages thereof,

In order to convey a definite idea of tho structure of the preferred forni of my maprooess carried out thereby in their proper order of sequence, and the mechanism wherm 'hy the steps are accomplished.

The ootton is first picked from the plants with the pods and introduced into the open end of a. neumatio conveyor-tube 1,in the nth of wllich is a suction fan or blower 2. V n the path of the tube is an agitator'casing 3 communicating with said tul e am] having therein a grid comprising spaced bars 4, between which pass a plurality of oppos elvrotatabie fingers 5 on iLgitELiDT-Shtdlfi fi. The

with the top 90f said casing.

Between the respoet-ivecylinders arepartitions 10, constituting mote-boards, which giartitions serve a dual purpose. They not only act as mote-boards to recoivs the loaf trash, (lust, bolls, and such like foreign so stances which havo boen rmovod fjirlli the cotton, but they also serve-tho {HEY-0S0 of I psirtitioning off the, air-blast, so as to provide iosd-chamber ll within the casing Z and 8 are provided with a number of rearward disposed pins, or in aotiml pl'lullfl: I prefer to 553% a iprfox nmtoly eleven thousand moms eggs hyliridor; but the number may he varied, if desired. inasnmcxh as the each of the cylinders, and each eparatingchambm'hns am mist-opening l3. At the 1' let-owning of es'vh srmiratmgwlmmhvr is a in sucli anmnnsr that the fingers wiii of said cylinders beingpreferab y parallel top of the casing is parsllr'i with the peri -1h ones of each of the sopomiormylmders, sspru rating-chambers 12 are formed ad wont; to

V ohi'ns, i wiii describe the various steps of the fingers are so arranged that the area of rotaiog which terminate adjacent to the teeth on the ylinders 8. Immediately above each 0 liner 8 is a beater 15, comprisi a shattv aving a plurality of diametrica y oppositely dis osed teeth, and below the partltions 10 and within the dead-chamber are cotton-removing devices, illustrated as brushes 16, which are secured to shafts driven by appro: priate means. Below the respective cylinders and within the dead-chamber is a conveyer com rising an endless belt 17, passing over the re lers 18 and 19, mounted on shafts 18 and 19 at the res ective ends of the conveyer and over the intermediate idlers 20. At the discharge end of the conveyor l7is a ho ,per 21 ,the bottom of which is closed by yie ding rollers 22, which have a tendency to rest one ainst the other, but; which may be separated y the cotton as it passes through said h per into a chute 23,where the cotton wi be conveyed to suitable premises provided for its reception. k

24 desi nates an accumulator-receptacle at the em? of the casing 7 remote from the blower 2, which receptacle 24 has communication with said casing 7 throu h an openin 25. The floor of the receptacle is provider with a hinged portion comprising a valve24, which may be dropped in the position indicated in dotted lines to permit the accumulated cotton to pass into the conveyer-tube 1 through the branch tube 27, which branch tube 27 is provided with a valve 28, similar to the valve 29in the tube. 1. Within the receptacle 24 is a rotatable separator-cylinder 8", having teeth thereon which receives the cotton as it is blown through the opening by the blast which exhausts through the exhirust-opening 25. As the cotton asses onto the teeth of the roller 3" it will 1c rcmoved by the brush l6, and in iwtual'practatod.

tice I prefer to have the first and last cylinders provided with com parati vel y short teeth while the intermediate cylinders are provided with comparatively long. teeth. The reason for this is that I desire to have the cotton acted upon by all of the cylinders in the machine.

The draft through the separating-ch amber 12 may be regulated by the valves 12'.

30 designates a drive-shalt which may rcceive its power from any suitable source, and 31 is the drive-shaft oi'thc blower. A belt 32 asses over pulleys on the drive-slnil'ts 30 am 31, whereby the blowcr-lan will be ro- (ln-a stub-shaft 33 is a pulley 34 and a pinion 35. A bell Zlli passes over the pulley 34 and over a pulley 37 on the drive-shalt 30, so that the rotation of thc drivc-slml't 30 will impart rotation to the shal't 33. The pinion 35 will impart motion to a gear 38 in mesh therewith, which gear is on one ol' the shal'ls 39 of the cylinders 3. Each shal't fill of each cylinder 8 projects through thc casing and carries a pulley-40, the internu-diale shal't carryin two of these. A belt 41 asses over a pulley on the first shaft and oviir a pulley on the intermediate shaft. A belt 42 asses over a pulley on the intermediate she. and over a policy on the last shaft,so that the rotation of the gear-wheel 38 will, through the medium of the belts 41 and 42, impart motion to all of the shafts 39.

43 designates a pulley on the shaft of'the first beater 15, around which ulley 43 passes a belt 44, also passing around a pulley 45 on the drive-shaft 30. A belt 46 passes over a pulley 43 and over a pulley 47 on the intermediate beater-shaft, and a belt 48 asses over a pulley 47 and over a ulle 49 on the end beater-shaft, so that -al of the heaters will be driven by the belt 44. A belt 50 passes over a pulley 51 on the shaft 30 and over a pulley 52 on the shaft of the first rotary brush 16, and as the shaft of each brush projects through the side of the casing 7 and as each brush-shaft carries a pulley similar to the one designated by the reference-numeral 52 the brushes may be driven from the pulley 52through the medium of the belts 53 and 54, respectively.

The beaters in the agitating-casing 3 may be driven in any suitable manner, and in order to avoid confusion no detail arrangement of earing is here illustrated.

it being assumed that all of the parts are properly assembled for proper operation, the steps carried out by the machine for cleaning the cotton willbe substantially as follows:

The valve 28 will be closed and the valve '29 open. By rotatin the shaft 30 all of the cooperating parts of Elle machine will be started in operation and the blower will suck in the cotton through the tube 1, and in the event that the agitator is utilized the bolls will strike a ainst the grid comprisim the bars 4, and, it living understood that the agitators will be driven by ap )ropriate mechanism, the bolls will be agitated by-thc revolving boaters, so as to loosen the md-cm'cring or bolls, which will then be drawn in through the blower and introduced into the casing 7.

The force of the blower will cause the cotton to intimately contact with the teeth on the iirst cylinder 8, which cotton will be )ressed and combed by the first comb 14, am as the 'lirst cylinder continues to rotatethc 'lirst beater 15 will come in contact with the mass of cotton and Foreign matter, and as it is intended to rotate the heaters at a comparatively greater speed than the rotation of the cylinders 8 the threshin action will be excrtcd against the m ss. lhe speed at which the heaters rotate compared to the s iced of rotation of the cylinders 8 is about t iirty to onc-- [Amati-s, the cylinders will preferably be arrnngia d p rota tc at about 'lil'ty rcvolu lions )cI' minute, while the spccd of rotation of the ln'utcrs will be about iil'tccn lnlndl'cd pcllllillutc.
